Loyal customers can be tough to find. So why do some companies run them off with crappy customer service? Often because the employees who care have no authority to fix problems, and those with the authority don't care. Today, let's hear the story of reader Boyd, his Dell XPS420, and the data corruption problems he had when running a disk array. Then let's hear how two other small service companies do much better support.

Boyd wanted a high powered desktop with RAID 0 (Redundant Array of Independent Disks). RAID 0 isn't really redundant, but it combines two drives into a single volume, spreading data across both physical drives which the user sees as one big drive.

Since two disks acting as one drive isn't typical on a desktop, Boyd carefully checked the Dell Web site to be sure the PC he wanted supported the feature. It did and he bought one. The Dell XPS420, with an Intel Quad Core Processor, starts at $799 and goes up depending on amount and type of memory, hard disk size and other details.

As often happens with PCs, things didn't go well (read about my fight with an HP running Vista). Turns out the RAID controller chip on the Dell XPS420 has been reported wonky on community forums, which explains why Boyd couldn't fix it. After multiple conversations with Dell support, they shipped him a replacement XPS420.

If only they'd read the original paperwork and configured the box the way Boyd had specified the first time around, things might be better. Dell didn't. It did send a tech to swap components around, but the disks would never work without corrupting the data.

Boyd had just about resigned himself to not having the disks done the way he wanted when someone from Dell corporate called him on Oct. 7. He remembers that date clearly because it's not often a corporate executive calls a customer and chews him out, telling him, according to Boyd, he had no other recourse and all the issues were of his own doing.

Unfortunately, he was so taken aback he didn't get the name, and Dell PR hasn't been very helpful. Of course, if they check their own phone records and find the person who made the call, I'd love to talk to him. He can explain how Boyd has caused RAID problems for all the other XPS420 owners looking for help on Dell's support forums.
